Hi.

I have a problem with a java UA-client when it is trying to generate a certificate on a sun platform. The application runs in weblogic and if I manually adds the certificto the pki folder the client starts fine. I can not see the same problem when i run the same client on windows.

The client uses: bcpkix-jdk15on-152.jar and bcprov-jdk15on-152.jar and I guess that this is what causes the problem. Perhaps a jar signing ? The UA stack is Prosys-OPC-UA-Java-SDK-Client-Binary-2.2.0-552

Best regards
.
